WINDOW-FRAME \VITI'I SASH-GORD HOLDER.

Application filed April 24,

Y '0 all whom it may concern Be it known that I, TrIoMAs CHms'rorrEL, acitizen of the United States, residing at St. Paul, in the county ofRamsey and State of Minnesota, have invented a new and usefulWindow-Frame with Sash-Cord Holder,

' of which the following is a specification.

My invention relates to window frames with removable sash, and theobjects are, first, to further improve upon the device covered by myUnited States Patent N 0. 1,135,662, issued April 13, 1915; secondly, tofurther provide means for suspending the sash weights before detachingthe sa'shes therefrom and for holding the sash cords within convenientreach of the operator when he returns the removed sash to the frame.

In the accompanying drawing :'Figure 1 is a vertical section about as onthe line 1-1 in Fig. 2 of a window frame and sash embodying myinvention. Fig. 2 is a vertical section substantially on the line 22 inFig. 1. Fig. 3 is a detail rear elevation of one of the sash cordretaining devices. Fig. 4 is a right hand edge View of Fig. 3 with thetiltable member of it in position for holding a sash cord, the latter isshown in dotted line as held in said member. Fig. 5 is a detail rearview of the mechanism by which the pocket closing strip 14 has its upperend attached to the window frame. Fig. 6 is a right hand edge view ofFig. 5 and portions of the wood work secured thereto. Fig. 7 is a frontelevation of the plate 29 in Figs. 5 and 6. Fig. 8 is a section on theline 8-8 in Fig. 2 with the link 24 intact and the pocket strip 14 infull line instead of dotted in its pushed back position in Fig. 2.

Referring to the drawing by reference numerals, 1O designates a windowframe having the usual pulleys 11 for sash cords 12 and sashes of whichonly one of each is shown. The frame is provided with the usual pocketstrip like 14 in Fig. 2 for the placing and. removal of sash weights(not shown) said strips being usually beveled at their ends as at 15 andheld by'a peg or screw 16 at the upper end and a screw 17 in the lowerend.

In each window frame having my invention one of said strips is modifiedas the strip 14, which has recessed into it at 18 and secured by nails19 or other means, a portion 20 of the parting, strip 20. Said strip 14may Specification of Letters Patent.

or may not have one edge beveled as at 21 in Flg. S to fit againstasimilar bevel 22 on the frame. The other edge of the strip is notbeveled but near its lower end it has a shallow recess 23 in which isplaced a link 24 having its upper end pivoted at 25 to the frame, andits lower end pivoted at 26 to the strip, so that it always occupies amore or less inclined position by which to give the strip a tendency toclose by its own weight. The upper end of the strip is also connected tothe frame by a link 27, shown in Fig. 2.

The link 27 is a fiat metal bar having at its lower end trunnions 28recessed into the strip 14 and retained therein as journals by aU-shaped plate 29, which is secured by screws 30 to the strip. Near themiddle of plate 27 are two lugs 31 in which are journaled trunnions 32of a bed plate 33, which is secured by screws 34 to the frame 10. Theupper end of the plate 27 is formed with a hook 35 adapted to be forcedinto and out of hooking engagement with the upper end 33 of the bedplate The .upper ends 36 of the plate 29 are slightly off-set so as tobe engaged and covered by the lower shoulders 37 of the plate 27.

Slightly higher up than the hook 35 is inserted and secured by screws38, in each sash channel of the frame a plate 39, which has an elongatedcentral aperture 40 (see Figs. 3 and 4) with cheeks 41 along the longeredges of the aperture, said cheeks project at right angles to the plateinto the wood of the frame, and between said cheeks is pivoted at piece43 having a notch 44 adapted to receive, and by tilting on its pivotpinch and hold the sash cord 12, the way shown in Figs. 1 and 4. Whensaid device is idle the tumbler 42 is held in the aperture 40 by havinga dent 45 engaged by a slight projection 46 on one of the cheeks 41.

In the operation of the invention when it is desired to remove thesashes from the frame for repair 01' for washing the windows, the sashcords are first attached in the catches 43, the inner or lower sash ispushed laterally against the strip 14 with sufficient force to unlockthe hook 35 and push the strip to the position shown in dotted line inFig. 2, this admits the sash so far into the opening the strip hadpreviously occupied that the opposite edge 47 of the sash will pass bythe window stop 48 (see'Fig. 2) and thus the sash may be pulled into theroom, the knots 19 of the cords 12 whereupon the pocket strip 14 isreplaced to normal position in the aperture in the frame. This is doneby simply pushing outward on the hook 35 until it interlocks with thetop edge 33* of the plate 33. The strip is held in closed position withsuflicicnt firmness by said hook and by having its beveled bottom endengaged with the inclined face 51 of the frame, in which lowere'dposition the strip is held by the links 24, 27. The inward movement ofthe strip is stopped by face 52 of the window stop 58, (see Fig. 8) andalso by the beveled faces 21, 22 and by the meeting of the small bevels54c and 549 of the portion 20 of the parting strip with the bevels 54and 54 of the portions 20 of it. All of said meeting surfaces and theplate 33 serve not only the mechanical purposes just described, but theyfurther serve to exclude cold draft through the pocket when the strip isin closed position. 55 in Fig. 1 designates a recess in the wood of theframe, so that if the hook 35 should ever stick, it can be loosened bythe point of a screw driver or similar tool inserted into said recessand tilted over the edge of the plate 39.

From the foregoing description it will be understood that my deviceobviates the ne cessity of climbing ladders to washwindows from theoutside as well as for hanging and removing storm sash and screens. Italso enables the sash cord to be secured to the frame before the sash isdetached and held in readiness for replacement into the sash whether thesash has been removed in the manner provided for by my side pocket stripor the sash has been removed in the old way, by removing first thewindow stop and entire strip.

What I claim is 1. A window frame having a side aperture large enoughfor either sash of the window to slip edgewise into it, a strip ar-'ranged in said aperture to'close it, and having each end attached to theframe by alink which allows the displacement ofthe strip into thesashweight pocket, the lower link occupying at all times a more or lessinclined position whereby the weight of the strip tends to close it andhold it closed, said strip arranged when closed to stop against thewindow stop, said strip having its lower end beveled and engaged with abeveled portion of the frame to aid in keeping the strip closed, andmeans for holding the upper end of the strip closed, said-holding meansfor the upper end of the strip comprising a bed plate secured on theframe adjacent the edge of the sash, a vertically oblong plate hingednear its middle to the lower end of the bed plate, and having its upperarm formed with a broad hook adapted when the arm is sprung by pressureto'eng'age over the top end of the bed plate, the other arm or portionof the oblong plate below said hinge being hingedly attached to thestrip so as to form the said upper link thereof. v

2. The structure specified in claim 1, said oblong plate having its linkportion or lower arIn reduced in width and the hinging of said upperlink to the strip, comprising trunnions on the link recessed'into theface of the strip and a U-shaped plate secured by screws to the stripand serving to keep the trunnions in the recesses; the arms of saidU-shaped plate straddling the link portion of the oblong plate andprojecting slightly up under the broader portion of the said oblongplate. 7

In testimony whereof I aflix'my signature.
